Boris Johnson—his next big interview

Following an uncomfortable 15 minutes with the BBC's Eddie Mair on Sunday morning, London Mayor Boris Johnson also has an in-depth interview with CNBC's Tania Bryer next month.

Johnson, who is widely considered a potential successor to British Prime Minister David Cameron, looked ill-at-ease in an interview on the BBC's The Andrew Marr Show, during which he was asked about fabricating quotes, an extramarital affair, and his friendship with controversial businessman Darius Guppy.

While the BBC focused on Johnson's political ambitions, Tania Bryer will ask the mayor about his upbringing and career path, focusing on the legacy of last summer's Olympic Games, with which he is highly associated, and the regeneration of East London, in next month's episode of CNBC Meets.

A deal was finalized last week to allow Premier League football club West Ham United to use London's purpose-built London Olympic Park as its home ground from 2016 onward. While the news means a "white elephant" will be avoided, the cost of conversion raises concerns about whether the 2012 games were worth the large bill for taxpayers.

The first episode of the new series of CNBC Meets saw Bryer talk with former President Bill Clinton in Little Rock, Arkansas.

Tania Bryer is a guest presenter and executive producer of CNBC Meets. In this series, she profiles some of the world’s most successful business people to find out what makes them tick. Bryer previously worked for BBC and Sky Television.
